UI improvement for highlights and notes

When the text has a highlight with a note, to delete the highlight you have to either edit the highlight and then choose delete (if you want to first see the note), or long press the highlight and choose unlight (this way you can't see the note). Would it be feasible to have a delete button show also in the note dialog? And related to that, how about a function to highlight and add a note with a single press (now you have to first highlight, and then tap the highlight to add a note).
